Figure 3. Chest radiograph and computed tomography (CT) showing empyema. The frontal chest radiograph (A) shows layering fluid in the right pleural space with an air-fluid level more medially, overlapping the right paramediastinal shadow (arrow) corresponding to the empyema. Enhanced axial CT images (B and C) show loculated fluid (asterisks) in the right pleural space with pockets of gas surrounded by a thick, enhancing rim (arrows) typical of an empyema. More caudally in the upper abdomen (D), hepatectomy changes are demonstrated post-resection of the previously noted large hepatic mass with regeneration of the left lobe
